Hello, I too have a server (Dell R720xd) with a BCM57800 NIC. I too am getting the message: WARNING: at /build/linux-s5x2oE/linux-3.2.46/drivers/net/ethernet/broadcom/bnx2x/bnx2x_main.c:8886 bnx2x_init_one+0xdc8/0x2b5d [bnx2x]()
I have 3 things to add from my investigation so far: (1) This is probably a bug against the Linux source package and not the bnx2x firmware package... I may try to reassign the bug in the following days. (2) I managed to get the broadcom provided driver to compile: I downloaded linux-7.6.62.zip from: http://www.broadcom.com/support/ethernet_nic/netxtremeii10.php Unzipped the zip and then found and unpacked netxtreme2-7.6.62.tar.gz therein. in the resulting directory: Server/Linux/Driver/netxtreme2-7.6.62/bnx2x/src I found that I had to patch bnx2x_compat.h as follows: ----------------------------------------------------- --- bnx2x_compat.h.orig 2013-03-13 00:30:56.000000000 +0000 +++ bnx2x_compat.h 2013-07-27 20:09:00.000000000 +0100 @@ -1621,11 +1621,11 @@ return index % n_rx_rings; } #endif -static inline void netdev_tx_completed_queue(struct netdev_queue *q, - unsigned int a, unsigned int b) { } -static inline void netdev_tx_reset_queue(struct netdev_queue *q) { } -static inline void netdev_tx_sent_queue(struct netdev_queue *q, - unsigned int len) { } +//static inline void netdev_tx_completed_queue(struct netdev_queue *q, +// unsigned int a, unsigned int b) { } +//static inline void netdev_tx_reset_queue(struct netdev_queue *q) { } +//static inline void netdev_tx_sent_queue(struct netdev_queue *q, +// unsigned int len) { } #endif #ifndef eth_hw_addr_random ----------------------------------------------------- Then I could just use make to compile up a new apparently working bnx2x.ko I have used this in the debian installer to network install the machine... but have not tested any more than that! (3) Looking at the error message it appears to be complaining in the function: bnx2x_init_one Comparing these between the debian source and the broadcom source shows there has been lots of changes!! BUT there are 2 that stick out: (a) early on in the function: +#if (LINUX_VERSION_CODE > KERNEL_VERSION(2, 6, 23)) /* BNX2X_UPSTREAM */ + /* + * The workaround will allow to HW properly handle the cases + * when device was not closed but started initialization process. + * This delay will cause to reset only the functions that belong + * to this OS in virtualized environment and also properly suits + * MF-modes. + */ + if (reset_devices) + msleep(5000); +#endif may be interesting... but also: (b) - max_non_def_sbs = bnx2x_get_num_non_def_sbs(pdev); - - /* !!!

That is all I have time for right now. Alex Owen
